In networking, the term topology is the way of connecting computers or nodes on a network. There are many ways in which computers are connected together in a computer network. Therefore network topology is defined as: the schemes of joining a number of computers in the form of a network are called Network Topologies.
We know that two or more devices are connected to a link for data communication. Similarly, two or more links form a topology. The topology of a network is the geometric representation of the relationship of all the links and the nodes (communication devices) to one another.
There are three commonly used network topologies. These are:
- Star topology
- Ring topology
- Bus topology
